I’m maybe pregnant; I need insights

My cycles can range from 26 days to 34 days. My son is 2 but nurses several times a day including at night.

About 12 days ago I had unprotected sex.

7 days after sex I had a small amount of blood. Literally a wipe and thats it.

Cheapie pregnancy tests at day 10 and 11 after sex were negative.

My cervical mucus is uncharacteristically stretchy and clear (mucus like). I also have been getting headaches, little bit of pelvic pain and sleepier than usual.

I wish I could either get a positive test or a period. Ughhhhhh

Edit- finally got my period
